How to process PayPal Express Checkout for third party merchants

May 18

This is a very simple one, but one that can take a lot of google-search-query-nuance tweaking to find.

It’s easy to find the documentation to do PayPal Express Checkout, but to find that one little field where you send an alternate user as the recipient of the payments, well that’s downright impossible. It is not in the docs (at least not as of this writing 5-18-2011).

Hi, thank you for this hint. It’s not well-documented in Paypal’s documentation and described poorly in Internet.

I’m implementing the same functionality now and I’ve got a question. I created two seller accounts in my Paypal sandbox: one is typical seller account and another is Payments Pro account. I’ve tried to pass each of them to Paypal sandbox services but no luck.

Passing any of these 2 accounts’ emails as a SUBJECT returns Paypal error 10423 “This transaction cannot be completed with PaymentAction of Authorization.” which is not documented at Paypal API Errors list.

Do you happen to know what’s wrong there? Is it a sandbox issue or I’m doing something wrong.
